On November 29, 1987, she left Wilmington Hospital around 6 PM, where she was assisting an AIDS patient, catching a lift on her way home on Route 40.

There were no signs of sexual assault, but she had been seriously abused, with her killer tying a string around her neck and hitting her head with a hammer before she died.

Like Ellis, she was killed by hammer blows and strangulation, but unlike the first murder, DiMauro's body was covered in blue fibers.

Special police forces, along with the FBI's profiling unit, concluded that a serial killer was operating in close proximity to Route 40.

Police and federal agents disguised as sex workers in attempt to gather information, with a task force of over 60 people being formed solely to capture the killer, but to no avail.

On September 14, 1988, Renée Taschner, an undercover police officer posing as a sex worker, roamed Route 40 in an attempt to capture the killer.

She refused, claiming that she was tired, but managed to tear some fiber from the blue carpet and write down the license plate number.

Upon examination of several license plates, it emerged that the vehicle belonged to Stephen Brian Pennell, a 31-year-old electrician, married and father of two, with no criminal record.

At the start of the trial, a panel of defense attorneys claimed that the initial fiber taken by Officer Taschner was obtained illegally because it was taken from his car.

Judge Richard Gebelein dismissed these allegations, saying that the carpet was visible to Taschner's eyes as soon as she opened the vehicle, so evidence from these fibers was legal.

Gebelein had to set a legal precedent and listen to the opinions of experts and scientists, who helped verify the DNA evidence.

Shortly after the decision, a bouquet of flowers was sent to the prosecutor's office, with a note reading: "You made us feel human again, from the women of Route 40."

He was the only defendant in Delaware's legal history to represent himself before the Supreme Court, and the only man convicted to willingly seek the death penalty.

Prior to the execution, numerous reporters tried to ask Pennell for exclusive interviews, hoping to reveal the location of Meyer's body.
